From 2d86ad37ece5fd064aa7c4fba5dd4378679c2cbf Mon Sep 17 00:00:00 2001 From: Peter Ujfalusi Date: Tue, 13 Nov 2012 09:28:46 +0100 Subject: [PATCH] mfd: twl-core: Clean up and correct child registration Make the twl child registration calls a bit more uniform by always using the SUB_CHIP_ID* define instead of the mixed use of the define and magic number. At the same time correct the following devices so they are registered for the correct parent device (i2c slave): twl4030_wdt is accessible on 0x4b address and not 0x48 twl4030_pwrbutton is accessible on 0x4b address and not 0x49 twl4030-audio is on 0x49 all the time Acked-by: Tero Kristo Signed-off-by: Peter Ujfalusi Signed-off-by: Samuel Ortiz --- drivers/mfd/twl-core.c | 27 ++++++++++++--------------- 1 file changed, 12 insertions(+), 15 deletions(-) diff --git a/drivers/mfd/twl-core.c b/drivers/mfd/twl-core.c index a55ab15ecf1..d666c9d454c 100644 --- a/drivers/mfd/twl-core.c +++ b/drivers/mfd/twl-core.c @@ -645,7 +645,7 @@ add_children(struct twl4030_platform_data *pdata, unsigned irq_base, if (IS_ENABLED(CONFIG_TWL4030_MADC) && pdata->madc && twl_class_is_4030()) { - child = add_child(2, "twl4030_madc", + child = add_child(SUB_CHIP_ID2, "twl4030_madc", pdata->madc, sizeof(*pdata->madc), true, irq_base + MADC_INTR_OFFSET, 0); if (IS_ERR(child)) @@ -661,8 +661,7 @@ add_children(struct twl4030_platform_data *pdata, unsigned irq_base, * HW security concerns, and "least privilege". */ sub_chip_id = twl_map[TWL_MODULE_RTC].sid; - child = add_child(sub_chip_id, "twl_rtc", - NULL, 0, + child = add_child(sub_chip_id, "twl_rtc", NULL, 0, true, irq_base + RTC_INTR_OFFSET, 0); if (IS_ERR(child)) return PTR_ERR(child); @@ -728,9 +727,8 @@ add_children(struct twl4030_platform_data *pdata, unsigned irq_base, } - child = add_child(0, "twl4030_usb", - pdata->usb, sizeof(*pdata->usb), - true, + child = add_child(SUB_CHIP_ID0, "twl4030_usb", + pdata->usb, sizeof(*pdata->usb), true, /* irq0 = USB_PRES, irq1 = USB */ irq_base + USB_PRES_INTR_OFFSET, irq_base + USB_INTR_OFFSET); @@ -778,9 +776,8 @@ add_children(struct twl4030_platform_data *pdata, unsigned irq_base, pdata->usb->features = features; - child = add_child(0, "twl6030_usb", - pdata->usb, sizeof(*pdata->usb), - true, + child = add_child(SUB_CHIP_ID0, "twl6030_usb", + pdata->usb, sizeof(*pdata->usb), true, /* irq1 = VBUS_PRES, irq0 = USB ID */ irq_base + USBOTG_INTR_OFFSET, irq_base + USB_PRES_INTR_OFFSET); @@ -804,22 +801,22 @@ add_children(struct twl4030_platform_data *pdata, unsigned irq_base, } if (IS_ENABLED(CONFIG_TWL4030_WATCHDOG) && twl_class_is_4030()) { - child = add_child(0, "twl4030_wdt", NULL, 0, false, 0, 0); + child = add_child(SUB_CHIP_ID3, "twl4030_wdt", NULL, 0, + false, 0, 0); if (IS_ERR(child)) return PTR_ERR(child); } if (IS_ENABLED(CONFIG_INPUT_TWL4030_PWRBUTTON) && twl_class_is_4030()) { - child = add_child(1, "twl4030_pwrbutton", - NULL, 0, true, irq_base + 8 + 0, 0); + child = add_child(SUB_CHIP_ID3, "twl4030_pwrbutton", NULL, 0, + true, irq_base + 8 + 0, 0); if (IS_ERR(child)) return PTR_ERR(child); } if (IS_ENABLED(CONFIG_MFD_TWL4030_AUDIO) && pdata->audio && twl_class_is_4030()) { - sub_chip_id = twl_map[TWL_MODULE_AUDIO_VOICE].sid; - child = add_child(sub_chip_id, "twl4030-audio", + child = add_child(SUB_CHIP_ID1, "twl4030-audio", pdata->audio, sizeof(*pdata->audio), false, 0, 0); if (IS_ERR(child)) @@ -1059,7 +1056,7 @@ add_children(struct twl4030_platform_data *pdata, unsigned irq_base, if (IS_ENABLED(CONFIG_CHARGER_TWL4030) && pdata->bci && !(features & (TPS_SUBSET | TWL5031))) { - child = add_child(3, "twl4030_bci", + child = add_child(SUB_CHIP_ID3, "twl4030_bci", pdata->bci, sizeof(*pdata->bci), false, /* irq0 = CHG_PRES, irq1 = BCI */ irq_base + BCI_PRES_INTR_OFFSET, -- 2.20.1
